FEATURE: Secure media allowing duplicated uploads with category-level privacy and post-based access rules (#8664)
### General Changes and Duplication

* We now consider a post `with_secure_media?` if it is in a read-restricted category.
* When uploading we now set an upload's secure status straight away.
* When uploading if `SiteSetting.secure_media` is enabled, we do not check to see if the upload already exists using the `sha1` digest of the upload. The `sha1` column of the upload is filled with a `SecureRandom.hex(20)` value which is the same length as `Upload::SHA1_LENGTH`. The `original_sha1` column is filled with the _real_ sha1 digest of the file. 
* Whether an upload `should_be_secure?` is now determined by whether the `access_control_post` is `with_secure_media?` (if there is no access control post then we leave the secure status as is).
* When serializing the upload, we now cook the URL if the upload is secure. This is so it shows up correctly in the composer preview, because we set secure status on upload.

### Viewing Secure Media

* The secure-media-upload URL will take the post that the upload is attached to into account via `Guardian.can_see?` for access permissions
* If there is no `access_control_post` then we just deliver the media. This should be a rare occurrance and shouldn't cause issues as the `access_control_post` is set when `link_post_uploads` is called via `CookedPostProcessor`

### Removed

We no longer do any of these because we do not reuse uploads by sha1 if secure media is enabled.

* We no longer have a way to prevent cross-posting of a secure upload from a private context to a public context.
* We no longer have to set `secure: false` for uploads when uploading for a theme component.

FIX: Allow secure uploads if global s3 setting active and enable_s3_uploads validations (#8373)
The secure media functionality relied on `SiteSetting.enable_s3_uploads?` which, as we found in dev, did not take into account global S3 settings via `GlobalSetting.use_s3?`. We now use `SiteSetting.Upload.enable_s3_uploads` instead to be more consistent.

Also, we now validate `enable_s3_uploads` changes, because if `GlobalSetting.use_s3?` is true users should NOT be enabling S3 uploads manually.

Krzysztof Kotlarek 69266f60ed FIX: tag and category watchers regression (#8336)
I made a regression here 17366d3bcc (diff-ddeebb36d131f89ca91be9d04c2baefaR10)

When the tag is added, people watching specific tag are notified but also people watching specific category.

Therefore, `notify_post_users` should accept options who should be notified.

So when `category` is added to the topic, users watching topic and users watching category are notified.

When `tag` is added to the topic, users watching topic and users watching tag are notified

Finally, when a new post is created, everybody is notified, topic watchers, category watchers, tag watchers.

FIX: Badge and user title interaction fixes (#8282)
* Fix user title logic when badge name customized
* Fix an issue where a user's title was not considered a badge granted title when the user used a badge for their title and the badge name was customized. this affected the effectiveness of revoke_ungranted_titles! which only operates on badge_granted_titles.
* When a user's title is set now it is considered a badge_granted_title if the badge name OR the badge custom name from TranslationOverride is the same as the title
* When a user's badge is revoked we now also revoke their title if the user's title matches the badge name OR the badge custom name from TranslationOverride
* Add a user history log when the title is revoked to remove confusion about why titles are revoked
* Add granted_title_badge_id to user_profile, now when we set badge_granted_title on a user profile when updating a user's title based on a badge, we also remember which badge matched the title
* When badge name (or custom text) changes update titles of users in a background job
* When the name of a badge changes, or in the case of system badges when their custom translation text changes, then we need to update the title of all corresponding users who have a badge_granted_title and matching granted_title_badge_id. In the case of system badges we need to first get the proper badge ID based on the translation key e.g. badges.regular.name
* Add migration to backfill all granted_title_badge_ids for both normal badge name titles and titles using custom badge text.

FEATURE: notify tag watchers when tag was added to post (#8299)
Issue was mentioned in this [meta topic](https://meta.discourse.org/t/send-a-notification-to-watching-users-when-adding-tag/125314)

It is working well when category is changed because NotifyCategoryChange job already got that code:
```
if post&.topic&.visible?
  post_alerter = PostAlerter.new
  post_alerter.notify_post_users(post, User.where(id: args[:notified_user_ids]))
  post_alerter.notify_first_post_watchers(post, post_alerter.category_watchers(post.topic))
end
```

For NotifyTagChange job notify post users were missing so it worked only when your notification was set to `watching first post`

Sam Saffron 3d85cc1e69 PERF: run expensive clean up uploads less frequently
Previously every hour we would run a full scan of the entire DB searching
for expired uploads that need to be moved to the tombstone folder.

This commit amends it so we only run the job 2 times per clean_orpha_uploads_grace_period_hours

There is a upper bound of 7 days so even if the grace period is set really
high it will still run at least once a week.

By default we have a 48 grace period so this amends it to run this cleanup
daily instead of hourly. This eliminates 23 times we run this ultra expensive
query.

Krzysztof Kotlarek 427d54b2b0 DEV: Upgrading Discourse to Zeitwerk (#8098)
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains. 

We no longer need to use Rails "require_dependency" anywhere and instead can just use standard 
Ruby patterns to require files.

This is a far reaching change and we expect some followups here.

Robin Ward d251f12c9c Tweak calculation for reviewable sensitivities/priorities
Previously, calculating thresholds for reviewables was done based on the
50th and 85th percentile across all reviewables. However, many forum
owners provided feedback that these thresholds were too easy to hit, in
particular when it came to auto hiding content.

The calculation has been adjusted to base the priorities on reviewables
that have a minimum of 2 scores (flags). This should push the amount of
flags required to hide something higher then before.
2019-09-19 14:07:56 -04:00
Robin Ward d5b52abf2f FIX: Require a min amount of reviewables before calculating thresholds
On forums with very few flags you don't want to calculate averages
because they won't be very useful. Stick with the defaults until we hit
15 reviewables at least.

FEATURE: send max 200 emails every minute for bulk invites (#7875)
DEV: deprecate `invite.via_email` in favor of `invite.emailed_status`

This commit adds a new column `emailed_status` in `invites` table for
 tracking email sending status.
 0 - not required
 1 - pending
 2 - bulk pending
 3 - sending
 4 - sent

For normal email invites, invite record is created with emailed_status
 set to 'pending'.

When bulk invites are sent invite record is created with emailed_status
 set to 'bulk pending'.

For invites that generates link, invite record is created with
 emailed_status set to 'not required'.

When invite email is in queue emailed_status is updated to 'sending'

Once the email is sent via `InviteEmail` job the invite emailed_status
 is updated to 'sent'.

Sam Saffron 74c4f926fc FIX: drop deleted posts from search index

1. Our "index grace period" has been wound down to 1 day, there is no point

mean for it to be removed

2. We were never dropping deleted posts from the index, only posts from
deleted topics

These changes speed up search a tiny bit and reduce background work.

This removes all uses of both `send` and `public_send` from consumers of

to test that a site setting is really there before sending an arbitrary
string to the class

ensure that the URLs are all up to date. Instead, we simply associate
uploads properly to `UserProfile` so that it does not have to replicate
the URLs in the table.

Guo Xiang Tan aa2311a7b0 FIX: Don't reindex posts belonging to a deleted topic for search.
Posts belonging to a deleted topic can't be index for search so we need
to avoid loading those post ids.

Guo Xiang Tan 3fc5dbb045 FIX: Don't attempt to reindex posts that have an empty raw.
If the post ids keep loading, we might end up in a situations where
we're always loading the same post ids over and over again without
indexing anything new.

Sam Saffron 9ebabc1de8 FEATURE: unconditionally update Topic updated_at when posts change in topic
Previously we would bypass touching `Topic.updated_at` for whispers and post
recovery / deletions.

This meant that certain types of caching can not be done where we rely on
this information for cache accuracy.

For example if we know we have zero unread topics as of yesterday and whisper
is made I need to bump this date so the cache remains accurate

This is only half of a larger change but provides the groundwork.

Confirmed none of our serializers leak out Topic.updated_at so this is safe
spot for this info

At the moment edits still do not change this but it is not relevant for the
unread cache.

This commit also cleans up some specs to use the new `eq_time` matcher for
millisecond fidelity comparison of times

Previously `freeze_time` would fudge this which is not that clean.
